Time is free, especially for recorded online courses. If it's in the form of a live class, it's gone.

The course is more flexible. Generally speaking, online courses can be viewed backwards, and so can live classes. You can record the screen and listen to your weaknesses repeatedly.

It saves the trouble and time on the way back and forth, especially for the little friends who live in inconvenient transportation.

Cheap, compared with offline courses, IELTS online courses are cheaper than offline courses.

In addition to its own advantages, IELTS online courses also have disadvantages, as follows:

Lack of consciousness, the common fault of young people in modern society is lack of self-discipline, and without supervision, it will form the habit of procrastination.

As an online class teacher, you don't need any assessment. Even if the students are not satisfied with the teacher and have already bought the class, it is impossible to get a refund.

Interactive, live class is better, if the IELTS course is recorded, you can only listen to what the teacher says, and you can't interact with the teacher at all. Some questions are difficult to answer at that time.
